How do I configure VPN passthrough with a PIX 501

Hi,

Sorry, newbie question...

I just recently installed a PIX 501 (version 6.3(1)) in my home
network.
Previously I was using a cheap airlink router that provided VPN
passthrough.
I'm using Nortel Contivity VPN client on 1 computer, and Cisco VPN
client on another client.

On my cheap Airlink router, I could easily use my Nortel or Cisco VPN
client to connect to my company with no configuration. These cheap
routers always advertise the ability to do VPN Passthrough.

I can't get the same thing to work on PIX 501.
I've read in other newgroups about NAT transversal, enabling isakmp,
etc, but nothing seems to work.

Do I have to actually configure any VPN settings on the PIX? I should
be able to simply configure an access-list. Do I need to configure
any transform-sets or crypto map, isakmp in order to make this to
work?

Thanks in advance,

Wallace

6.3(1) has several known security problems. There are operational
problems with 6.3(2), and security problems in 6.3(3), 6.3(4),
6.3(5), and 6.3(5)112 . It would be best if you could upgrade
your PIX 501 as far as possible. If you are the registered owner
of the device, the upgrade is free.

You only need to configure transform sets and crypto maps and
isakmp nat-traversal if you are terminating the VPN at the PIX.
